Metals are natural components of the earth and exist in many forms - each with its own specific chemical characteristics that define its interactions with the environment and with living organisms.

Typical risk assessments and guidance materials have been designed for organic chemicals and as such fail to take into consideration of metals specificities. This guidance looks to provides detailed advice needed to perform accurate risk assessments for metals.

  1. Risk characterisation – general aspects.

  2. Exposure assessment.

  3. Effects assessment.

  4. Marine risk assessment.

  5. Bioavailability – water, sediment and soils.

  6. Bioavailability – water, sediment and soils (continued).

  7. Uncertainty analysis.

  8. Classification.

  9. Weight of evidence.
